53711 - message body not show with weird content-type

Status: NEW

(MailNews Core :: MIME, defect)

Description

[Henrik Gemal]

Attached is a mail with a rather weird content-type (x-application-newsgroup). 
The multipart/mixed attached in the mail has some headers and then two return, 
which should tell Mozilla that the next lines are the body, so Mozilla should 
show them.
With the attached mail I'd expect to see on my screen:
Path: 
news.inet.tele.dk!news.netscum.dk.MISMATCH!CensurBot!news.tele.dk!n=ot-for-mail
From: "kokken" <[e-mail]>
etc etc etc...

Mozilla seems to ignore the two returns and treat the next lines are more 
headers, which I think according to the spec is wrong....

Henrik, did you in fact see *any* message body?  If the headers that were part 
of the attachment were somehow being interpreted as part of the headers *for* 
the attachment, wouldn't you have expected to see the content?

I've interpolated your message into my mail system, and for me, it shows up 
entirely blank.  I think what is happening here is that 
  Content-Type: x-application-newsgroup
is not a recognized MIME type, and Mozilla doesn't show anything inline that it 
doesn't know how to handle.

There may be an RFE somewhere about displaying unknown types as plain text, but 
I can't find it right now.
